Step 4 · Record, Label, and Double-Check

This final check is key to a flawless installation. In your notebook, create a clear list pairing the width and depth for every single step number. It's not uncommon for stairs in older homes to have slight variations, so if you find any steps with unique dimensions, place a small piece of masking tape on that step's riser and label it with the corresponding number from your notes. If you're looking for that perfect, custom-made to fit solution, taking a quick photo of any unusual steps is a fantastic idea to share. Before you finish, double-check all your numbers one last time. This diligence now gives you peace of mind later and ensures your new treads will fit perfectly.
